It's probably a Pentium of some sort, so I assume it's a PCI/AGP interface, probably a pre-PICMG or PICMG competitor based on it being an industrial SBC, but I have never seen one like this before.
Looks very similar to EISA but also similar to how AGP looks connector wise but isnt either of them.
PISA.
PCI+ISA buses in what mechanically looks like an EISA slot.
You need a PISA backplane.
Edit:
Given the chips on it, I'd say it's Mendocino or Coppermine with an i440ZX/BX or i815 chipset.
I find it very interesting that it has an ESS Soundchip on it.
PISA (PCI+ISA) and it's a socket370 not a Pentium:

a fanless Celeron variant exists:

for this one you technically need no backplane at all, it has everything on board and can be run completely independent if you don't want to add any other add-on cards.
